just finished to breadboard this little beast...
it sounds really great with filter included!
I suggest to everyone to build one... it's going to be a lot of fun!
now it's time to etch a cool PCB...

ok, I will. It will take a few days, maybe a week, 'cause I only have a handsketch right now, so I have to create a good diagram on my PC, but I don't have any dedicated software, so I will have to do it with paintbrush (like I did for my WP20), which is a windows standard and poor sw to make images...

ladislao,

I'm doing most my artwork in an excellent little dtp program called 'Intaglio'. Unfortunately, it only works on Mac OSX- but if you want me to help out, please email me and I'll do the layout for you :)

Hi Tom,
thanks for your proposal... I will try first with my rudimental tools (they make me feel like a pioneer or something...), then, if I get in trouble, I will write you an email...
If you come along with a PCB for the WSG before I post mine, please post it here... it could be helpful as a reference for me also

The two pictures you will find inside the compressed folder are bigger than real dimensions, so you will have to reduce the images’ scale in order to use them to etch a usable board.

This board is supposed to receive all the components (jack, pots and switches included), with no flying wires, so you will probably have to adjust the position of the “solder-points” (are they called pads? sorry for my lame English) for S1, S2 and J1, in order to fit the pinout of the components in your hands.

The spacing among the pads of the potentiometers is dimensioned to receive mini-pots (guitar pedal type pots).

In the parts layout picture you will see that C6 is shown as a rectangular component (not oval like the other ceramic capacitors). This is because I couldn’t find a Ceramic Disk Type Capacitor of 1uF, so I had to buy a poly capacitor of the same value.

In the board you will also find these additional components:

Led: on the bottom-left corner of the PCB – this is to show the on/off status of the unit.

Rk: is a resistor used to give the proper voltage to the Led. Choose the value you prefer.

Vol. Pot. = 100K – this is just a Volume pot.

I HAVEN’T BUILT AND TESTED THIS PCB YET, SO PLEASE TRIPLE-CHECK THE CONNECTIONS AMONG THE COMPONENTS BEFORE ETCHING YOUR BOARD, IN ORDER TO AVOID TROUBLES AND WASTE OF TIME&MONEY!!!

There is only one thing that really confuses me. I haven't checked it against the schem and you kind of addressed it. Whats up with all the
"pads" for s1 and s2 there seems to be six for each and two and the
ground(i think thats what it is) and some of the six pads don't even connect to a trace. I'm sure I can try and follow the schem, but what are
the two or four pads and the bottom rail for?

*the two pads connected together on the bottom side:
these two pads will receive two pins coming from a metal shield protecting the switch. it is a ground connection and you will not find it in the schem.
I've done this connection just due to the fact that I have this pins coming from the switch. If your switches don't have a ground pin(s), just forget about it and go straight along.

*group of six pads:
the switches I found at my electronics shop were two poles switches (this means that inside the switch you have two separate contacts, with three pins/pads for each contact), for S2 it works just fine because in this way I had the opportunity to interrupt both wires coming from the battery (don't know if it is really useful or not); for S1 a single pole switch would be ok, but as I told you, I couldn't find 'em around so I decided to mount a two pole switch using only one of these two poles. As you can see only the pads on the right side of S1 are used. the other pads are not connected because we don't need them in the circuit. If you have a single pole switch connect it to the two pads on the right side of S1 and you'll be fine...

Lorenzo you are the MAN. Thats completely cool. I hope people have fun with it. It really is a simple little starter project for people to goof around with. I haven't walked through your board layout but I trust your building skills.

Nice layout and I like dnny's mp3 too.

Cheers All_________________There 10 kinds of people in this world that understand binary those that do and those that don't.

Thanks Ray for your words...
But please, when you have a few minutes to spend on my board, check it out and let me know your opinion, so other people on this forum can etch a board with no risk of mistakes and waste of time/money...
bye
